Additional data files that contain information directly supportive of the document, for example, an audio clip, movie, database, spreadsheet, applet, or other external file
This element has a similar function to the <audiovisual> element in some XML tag sets and the <unprinted-item> element (used only for electronic files) in other tag sets.
The element is used in two senses: first, inside the article front matter as an alert to the existence of supplementary material; and second, as part of the textual flow, where it is similar to a Figure, in that it can be positioned as a floating or anchored object and may take a caption.
For the second usage, the position attribute may be used to indicate whether this element must be anchored at its exact location within the text or whether it may float, for example, to the top of the next page, into the next column, to the end of a logical file, or within a separate window. The mimetype attribute may be used to identify a file type for a <supplementary-material> element.
Conversion Note: <supplementary-material> may contain a preview image (e.g., the first frame of a movie, tagged as a <graphic> or <media>), with the caption/preview placed in a manner similar to a Figure and a cross-reference made to the material from the text.
